K-band spectroscopy of IGR J16358-4726 and IGR J16393-4643: two new symbiotic X-ray binaries
E. Nespoli, J. Fabregat, R. E. Mennickent
Symbiotic X-ray Binaries (SyXBs) are a recently discovered subclass of Low Mass X-ray Binaries. Their growing number makes them an important evolutionary channel of X-ray Binaries.…
The evolution of the timing properties of the black-hole transient GX 339-4 during its 2002/2003 outburst
T. Belloni, J. Homan, P. Casella +5
We present the results of the timing and color analysis of more than two hundred RXTE/PCA observations of the bright black-hole transient GX 339-4 obtained during its 2002/2003 out…
Unveiling the nature of IGR J16493-4348 with IR spectroscopy
E. Nespoli, J. Fabregat, R. E. Mennickent
The International Gamma-Ray Astrophysics Laboratory (INTEGRAL) is discovering a large number of new hard X-ray sources, many of them being HMXBs. The identification and spectral ch…
Detection of a large Be circumstellar disk during X-ray quiescence of XTE J1946+274
M. Ozbey Arabaci, A. Camero-Arranz, J. Gutierrez-Soto +6
We present a multiwavelength study of the Be/X-ray binary system XTE J1946+274 with the main goal of better characterizing its behavior during X-ray quiescence. We aim to shed ligh…
GX 339-4: back to life
T. Belloni, E. Nespoli, J. Homan +4
We report preliminary results of a RossiXTE campaign on the 2002 outburst of the black-hole candidate GX 339-4. We show power density spectra of five observations during the early…
New insights into the Be/X-ray binary system MXB 0656-072
E. Nespoli, P. Reig, A. Zezas
The X-ray transient MXB 0656-072 is a poorly studied member of high-mass X-ray binaries. Based on the transient nature of the X-ray emission, the detection of pulsations, and the e…
